研究人员对 11 个用于红餐酒的葡萄和葡萄汁样品进行了调查，以确定是否存在潜在产生赭曲霉毒素 A (OTA) 的霉菌。从这些样品中分离出 59 种丝状真菌和 2 种酵母。在分离的 30 个属中，半知菌属最常见（70%），其次是子囊菌属（10%）。十一个葡萄样品中有六个受到潜在的赭曲霉毒素菌株（产黄青霉和碳曲霉）的污染。当在固体复合培养基上进行体外培养时，14 种碳曲霉菌株产生了 OTA。在相同条件下没有其他物种产生 OTA。在必须的样品中，11 个样品中有 8 个被发现受到 OTA 污染（浓度来自
Eleven samples of grapes and musts used in red table wines were investigated for the occurrence of potential ochratoxin A (OTA)-producing molds. From these samples, 59 filamentous fungi and 2 yeasts were isolated. Among the 30 genera isolated, Deuteromycetes were the most frequent (70%) followed by Ascomycetes (10%). Six of the eleven grapes samples were contaminated by potentially ochratoxinogenic strains (Penicillium chrysogenum and Aspergillus carbonarius). When cultivated in vitro on solid complex media, the 14 strains of A. carbonarius produced OTA. No other species produced OTA under the same conditions. Among must samples, eight of eleven were found to be contaminated by OTA (concentrations from
